Effects of Functional Training on Physical Function,Cardiorespiratory Fitness,and Quality of Life in Older Women: A 6-Week Randomized Controlled Trial

Abstract

Background: Functional training is increasingly recognized for its potential to improve physical function and quality of life (QoL) in older adults. This randomized controlled trial examined the effects of a six-week functional training program on physical function, cardiorespiratory fitness, and QoL in older women. Methods: Fifty older women (mean age: 63.5 ± 3.7 years) were randomly assigned to a functional training group (n = 25) or a control group (n = 25). The intervention group participated in a six-week functional training program (six sessions per week), while the control group maintained usual daily activities. Outcomes included dynamic balance (TUG test), flexibility, muscle strength, walking speed, cardiorespiratory fitness (two-minute step test), and QoL. Results: Functional training significantly improved dynamic balance, lower body flexibility, lower body strength, walking speed, and aerobic endurance (p < .05 for all). QoL significantly increased in the functional training group across all domains, as well as overall scores (p < .05). However, the control group experienced declines in some measures. Conclusion: Functional training is a safe and effective intervention for improving physical function, cardiorespiratory fitness, and QoL in older women. The significant enhancements in physical and mental health highlight its value in promoting independence and well-being in aging populations. Future studies should explore its long-term benefits and scalability.
